toptens trainer on Amazon it's by far the best on Amazon and one of my favorite flippers Here Better than my squiddy imo

This one is solid and feels premium with a bit of tuning but really heavy at 8 oz . However I feel like this is one of the best trainers on Amazon from my experience . Sturdy and good overall trainer. Runs for 17$ usd

This one is lighter and has good handles . I’ve ordered it but still waiting on it to come . I’ve heard good reviews as the best amazon trainer . Look up the reviews online or on YouTube but I can’t say much since I don’t have it yet different colors so just look around recommended or look up the color itself . About 26 $ usd
